We're dividing 454163 by 20 
We're looking to find how many times 20 goes into 454163.

Step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 20

Let's proceed to step 2:
When dividing 45 by 20, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 40 away from 45, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 20

Step 3:
If we divide 54 by 20, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 40 from 54 and we're left with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 20

Advancing to step 4:
20 can be fit into 141 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 227.0
If we take 140 away from 141, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 20

Moving on to step 5:
The number 20 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 2270.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 20

Let's proceed to step 6:
20 can be fit into 163 8 times, resulting in a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 22708.0
Subtract 160 from 163 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 22708.1
Deduct 20 from 30 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 22708.15
If we take 100 away from 100, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22708.15
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22708.15
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 22708.15 and a remainder of 0.0.
